3 Claims.

The present invention relates to new and useful improvements in weldershelmets, and more particularly to means for ventilating the inside ofthe helmet and thus to cool the head of the person Wearing the same.

An important object of the present invention is to provide means forattaching an air hose to the head band to which the helmet is pivotallyattached and without interfering with the move.- ment of the helmet intoits raised or lowered position.

A further object is to provide a device of this character of simple andpractical construction, which is efficient and reliable in operation,relatively inexpensive to manufacture and attach in position to thehelmet without necessitating any material changes or alterations thereinand which otherwise is well adapted for the purpose for which the sameis intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likereference numerals refer to like parts throughout, and in which:

Figure l is a side elevational View with parts broken away and shown insection,

Figure 2 is a rear elevational View, and

Figure 3 is a fragmentary sectional view taken substantially on a line3-3 of Figure 2.

Referring now to the drawings in detail, wherein, for the purpose ofillustration, I have disclosed a preferred embodiment of the invention,the numeral 5 designates a welders helmet of conventional constructionand which includes horizontal and vertical head bands 6 and 1. One ofthe sides of the helmet is pivotally attached by means of a pin 8 to thevertical head band 1 to provide for the raising and lowering of thehelmet in front of the face of a person.

The helmet 5 and head bands 6 and l are of conventional construction,and accordingly a detailed explanation thereof is not believednecessary.

To the vertical band I is secured a pair of split clamps 9 by means ofwhich a pipe T is clamped in position on top of the head band.

A hose H is attached at one end to the rear end of the T I0 and extendsdownwardly at the back of the helmet and is attached to the belt orother suitable garment of the welder at the waist thereof by means of aconventional form of resilient fastener I2. The hose H leads to asuitable source of compressed air, and at its point of attachment to thebelt or other garment of the welder, the hose II is provided with amanually controlled valve I3.

A pair of flexible hose l4 and I5 extend from the sides of the fittingl9 and are attached in a forwardly extending position at the sides ofthe horizontal head band 6 by means of clamps l6.

Accordingly, in the operation of the device, air is admitted into thehose II by the opening of the valve I3 and is discharged forwardly atthe inside of the helmet 5 at opposite sides of the horizontal head band6 for circulation around the head of the wearer and thus serve to coolthe head of the person wearing the helmet.

In view of the foregoing description taken in conjunction with theaccompanying drawings, it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though I have herein shownand described a preferred embodiment of my invention that the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

What I claim is:

l. A ventilating attachment for welders helmets of a type including ahorizontal and a vertical head band, a T fitting attached to thevertical head band, an air hose attached to said T fitting and extendingdownwardly behind the helmet, and a pair of hose sections attached tosaid fitting at the sides thereof and extending downwardly into thehelmet at the sides of the horizontal head band.

2. A ventilating attachment for welders helmets of a type includinghorizontal and a vertical head band, a T fitting attached to thevertical head band, an air hose attached to said T fitting and extendingdownwardly behind the helmet, a pair of hose sections attached to thesides of said fitting and extending downwardly and forwardly at thesides of the horizontal head band and means for attaching said hosesections to the sides of the horizontal head band.

3. A ventilating attachment for welders helmets of a type including ahorizontal and a vertical head band, a T fitting attached to thevertical head band, an air hose attached to said T fitting and extendingdownwardly behind the helmet, a pair of hose sections attached to thesides of said fitting and extending downwardly and forwardly at thesides of the horizontal head band, and means for attaching said hosesections to the sides of the horizontalhead band, means for attachingthe first-named air hose to the back of a person, and a valve in saidair hose.
